(CNN) - Sen. John McCain moved to shore up his support among conservatives by pledging Tuesday to nominate strict-constructionist judges to the federal bench.
"It will fall to the next president to nominate hundreds of qualified men and women to the federal courts, and the choices we make will reach far into the future," the presumptive Republican presidential nominee said during a speech at Wake Forest University in North Carolina.
"My two prospective opponents and I have very different ideas about the nature and proper exercise of judicial power," he said, referring to Sens. Hillary Clinton and Barack Obama. "We would nominate judges of a different kind, a different caliber, a different understanding of judicial authority and its limits."
Many conservative members are suspect of McCain on the issue of judges because of his involvement in 2006 in the so-called Senate "gang of 14." That bipartisan group of senators sought to reach a consensus on President Bush's judicial appointees, blocking some of the president's most conservative nominations while promising to confirm others.
The group formed after the then-Senate Majority Leader Bill Frist threatened to remove the ability to filibuster judicial nominations after Democratic senators blocked a number of President Bush's nominees.
McCain also directly criticized Obama for not voting to confirm Justice Samuel Alito, saying the Illinois senator's justification of that decision sounded like it was written by an "activist judge."
"Apparently, nobody quite fits the bill except for an elite group of activist judges, lawyers, and law professors who think they know wisdom when they see it – and they see it only in each other," McCain said of Obama.
In response to McCain's speech, Democratic National Committee Chairman Howard Dean said the Arizona senator has a "radical, right wing judicial philosophy."
"It's clear he's the wrong choice to safeguard that future," Dean also said. "No matter how far they have gone to restrict our fundamental rights or their clear records of gutting the reforms John McCain claims to care about, he has put loyalty to his party and a radical agenda ahead of the American people."
